What are vaping coils or mod coils?
If you just started vaping or expanding your knowledge about vaping, learning about coils is an absolute must. Vape wires are the heart of your mod. Vapers are crazy finding the best coil build for their vapes. Although widely known as vape coils they are technically atomizer heads. The coil is a component inside the atomizer. It plays an important role in heating the e-liquid and vaporising it.
When you fire your vape device an electric current runs from the battery and into your coil wire, the amount of electrical resistance, or ohms, determines how quickly that wire will heat up. The Ohm rating of any given coil depends on a number of factors including length of wire, style of coil wrap, amount of wires and gauge of the coil wrap.
There are different wire types that some vapers use and most atomizer coils are made from Nichrome or Kanthal.
Here are some other wire materials used in vape coils:
- Stainless steel
Each type of coil offers a different vaping experience and different benefits. The type of coil is largely determined by the material used to make the vape wire and also the resistance of the wire.
Explore more about the different vaping coil materials here:
The original coil material, easy to work with, it is malleable and works only in Power Mode. Kanthal is easy to work with if you’re building coils. It is sturdy while still being easy to manipulate. Coils made from kanthal will work with any vaping device on the market.
An alternative to Kanthal, Nichrome is arguably more flavorful than Kanthal with a quicker ramp-up time. On the other hand, it is prone to burning and melting more easily. Also only useable in Power Mode. Nichrome is a little harder to work with than kanthal and that’s why it has fallen out of favor with vapers.
It’s also known for its durability and longevity. Stainless steel is the most versatile option and works in both Temperature Control and Power Mode.
Nickel is a very soft metal providing the quickest ramp-up time and excellent flavor. On the down side, it’s softness can make it hard to work with and it only works with Temperature Control.
Titanium can be highly flammable and has some general health and safety concerns regarding its use but it is one of the only options for those with severe nickel allergies. It is also the most expensive wire option and only compatible with Temperature Control.
What is coil resistance?
Resistance (ohms) is a measure of how much the wire resists or reduces the amount of electrical current flowing through it. The higher the resistance, the lesser vapor production you’re going to get. Resistance also influence the style of vaping for which a coil is suitable. Sub-ohm vaping is generally considered the territory of direct-to-lung vaping while resistances above one ohm is typically used with mouth-to-lung vaping.
There are two categories for atomizer heads; high and low resistance
High Resistance Coil:
An atomizer head with a resistance above 1.0 ohm. Generally used at a lower power and are more suited for “regular” vapour production.
- Smaller clouds of vapour
- Consume less e-liquid
- Suitable to most e-cigs
Low resistance coil
An atomizer head with a resistance less than 1.0 ohm. Commonly referred to as “sub-ohm”. Generally, requires higher powers.
- Larger clouds of vapour
- Uses more e-liquid
- Not suitable for all e-cigs
Other frequently asked questions about vaping coils
You will know when to replace the coil because you get a distinct ‘burnt toast’ flavour once they die. Usually it will take 4-15 days for a sub-ohm type and around 3-4 weeks for pen type.
The most common reason is either the coil has become flooded or the tank has a crack or fracture.
Most common issue is the device on and off confusion because of the multiple clicks of the firing button. But generally, it’s because the coil has passed its life span and is no longer working.
So don’t be afraid to try and explore finding the best coil build for mech mod that you have. Figure out your own personal sweet spot! Experimentation is one of the many joys of vaping.
